-/**
- * ApcUniversalClassLoader implements a "universal" autoloader cached in APC for PHP 5.3.
- *
- * It is able to load classes that use either:
- *
- *  * The technical interoperability standards for PHP 5.3 namespaces and
- *    class names (https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-0.md);
- *
- *  * The PEAR naming convention for classes (http://pear.php.net/).
- *
- * Classes from a sub-namespace or a sub-hierarchy of PEAR classes can be
- * looked for in a list of locations to ease the vendoring of a sub-set of
- * classes for large projects.
- *
- * Example usage:
- *
- *     require 'vendor/symfony/src/Symfony/Component/ClassLoader/UniversalClassLoader.php';
- *     require 'vendor/symfony/src/Symfony/Component/ClassLoader/ApcUniversalClassLoader.php';
- *
- *     use Symfony\Component\ClassLoader\ApcUniversalClassLoader;
- *
- *     $loader = new ApcUniversalClassLoader('apc.prefix.');
- *
- *     // register classes with namespaces
- *     $loader->registerNamespaces(array(
- *         'Symfony\Component' => __DIR__.'/component',
- *         'Symfony'           => __DIR__.'/framework',
- *         'Sensio'            => array(__DIR__.'/src', __DIR__.'/vendor'),
- *     ));
- *
- *     // register a library using the PEAR naming convention
- *     $loader->registerPrefixes(array(
- *         'Swift_' => __DIR__.'/Swift',
- *     ));
- *
- *     // activate the autoloader
- *     $loader->register();
- *
- * In this example, if you try to use a class in the Symfony\Component
- * namespace or one of its children (Symfony\Component\Console for instance),
- * the autoloader will first look for the class under the component/
- * directory, and it will then fallback to the framework/ directory if not
- * found before giving up.

 ClassLoader Component
 =====================
 
-ClassLoader loads your project classes automatically if they follow some
-standard PHP conventions.
-
-The Universal ClassLoader is able to autoload classes that implement the PSR-0
-standard or the PEAR naming convention.
-
-First, register the autoloader:
-
-    require_once __DIR__.'/src/Symfony/Component/ClassLoader/UniversalClassLoader.php';
-
-    use Symfony\Component\ClassLoader\UniversalClassLoader;
-
-    $loader = new UniversalClassLoader();
-    $loader->register();
-
-Then, register some namespaces with the `registerNamespace()` method:
-
-    $loader->registerNamespace('Symfony', __DIR__.'/src');
-    $loader->registerNamespace('Monolog', __DIR__.'/vendor/monolog/src');
-
-The `registerNamespace()` method takes a namespace prefix and a path where to
-look for the classes as arguments.
-
-You can also register a sub-namespaces:
-
-    $loader->registerNamespace('Doctrine\\Common', __DIR__.'/vendor/doctrine-common/lib');
-
-The order of registration is significant and the first registered namespace
-takes precedence over later registered one.
-
-You can also register more than one path for a given namespace:
-
-    $loader->registerNamespace('Symfony', array(__DIR__.'/src', __DIR__.'/symfony/src'));
-
-Alternatively, you can use the `registerNamespaces()` method to register more
-than one namespace at once:
-
-    $loader->registerNamespaces(array(
-        'Symfony'          => array(__DIR__.'/src', __DIR__.'/symfony/src'),
-        'Doctrine\\Common' => __DIR__.'/vendor/doctrine-common/lib',
-        'Doctrine'         => __DIR__.'/vendor/doctrine/lib',
-        'Monolog'          => __DIR__.'/vendor/monolog/src',
-    ));
-
-For better performance, you can use the APC based version of the universal
-class loader:
-
-    require_once __DIR__.'/src/Symfony/Component/ClassLoader/UniversalClassLoader.php';
-    require_once __DIR__.'/src/Symfony/Component/ClassLoader/ApcUniversalClassLoader.php';
-
-    use Symfony\Component\ClassLoader\ApcUniversalClassLoader;
-
-    $loader = new ApcUniversalClassLoader('apc.prefix.');
-
-Furthermore, the component provides tools to aggregate classes into a single
-file, which is especially useful to improve performance on servers that do not
-provide byte caches.
+The ClassLoader component provides tools to autoload your classes and cache
+their locations for performance.
 
 Resources
 ---------
 
-You can run the unit tests with the following command:
-
-    $ cd path/to/Symfony/Component/ClassLoader/
-    $ composer.phar install
-    $ phpunit

-/**
- * UniversalClassLoader implements a "universal" autoloader for PHP 5.3.
- *
- * It is able to load classes that use either:
- *
- *  * The technical interoperability standards for PHP 5.3 namespaces and
- *    class names (https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-0.md);
- *
- *  * The PEAR naming convention for classes (http://pear.php.net/).
- *
- * Classes from a sub-namespace or a sub-hierarchy of PEAR classes can be
- * looked for in a list of locations to ease the vendoring of a sub-set of
- * classes for large projects.
- *
- * Example usage:
- *
- *     $loader = new UniversalClassLoader();
- *
- *     // register classes with namespaces
- *     $loader->registerNamespaces(array(
- *         'Symfony\Component' => __DIR__.'/component',
- *         'Symfony'           => __DIR__.'/framework',
- *         'Sensio'            => array(__DIR__.'/src', __DIR__.'/vendor'),
- *     ));
- *
- *     // register a library using the PEAR naming convention
- *     $loader->registerPrefixes(array(
- *         'Swift_' => __DIR__.'/Swift',
- *     ));
- *
- *
- *     // to enable searching the include path (e.g. for PEAR packages)
- *     $loader->useIncludePath(true);
- *
- *     // activate the autoloader
- *     $loader->register();
- *
- * In this example, if you try to use a class in the Symfony\Component
- * namespace or one of its children (Symfony\Component\Console for instance),
- * the autoloader will first look for the class under the component/
- * directory, and it will then fallback to the framework/ directory if not
- * found before giving up.
- *
